Over-The-Cab Height Clearance Manual
Prevent $200,000 peeling roof strikes under low railroad overpasses. Enforce physical measuring stick protocols, tractor air suspension dump interlocks, and automated bridge height routing.
Physical Height Stick Audit
Never rely on vehicle spec sheets. High-profile roof racks, sunroof visors, and oversized SUV tires raise loaded clearance. Measure the highest vehicle point using an aluminum height stick before rolling.
Air Suspension Dump Valve
If tractor drive air bags over-inflate or ride-height control valves fail, loaded height climbs by up to 3.5 inches at highway speed. Monitor air suspension pressure telemetry continuously.
Parkway & Overpass Routing
Standard consumer GPS units route commercial haulers onto low-clearance parkways (e.g., Long Island / New York parkways with 8-foot stone arches). Exspeedite enforces strict truck-specific bridge routing.
Exspeedite Loaded Height Laser Photo Verification
Drivers photograph the height stick reading at the highest vehicle point (Slot 1 over-cab or Slot 4 top-deck) into the mobile dispatch app, certifying clearance under 13'6" or 14'0".
